hey... here's ur answer !!
1 ) sin i / sin r = constant
sin i / sin r = ñ
where ñ is called as refractive index.
2) statement :-
" the ratio of sin of angle of incidence to the sin of angle of refraction is constant for given pair of media and colour ."
3) Refractive index is pure no. it does not have any unit.
hope it might be helpful :) ##

Snell's law is used to describe a relation between the angle of incidence amd the angle of refraction when light travels from one one media to another, like air,water,or glass etc...
Snell's law states that the ratio of the sines of the angles of incidence and refraction is equivalent to the ratio of phase velocities in the two media, or equivalent to the reciprocal of the ratio of the indices of refraction.
